Steam Siege was the last set in XY to feature Break cards, and included dual-type card, where Pokemon would have two types, allowing them to attack a wider range of targets for weakness. For collectors, Steam Siege has not always been the most popular set and suffers from having been released at the end of the XY era and being followed by Evolutions, which sparked nostalgia in collectors. Nevertheless, the set includes some very collectable cards, particularly the EX versions (both Mega and regular) of Gardevoir, Volcanion, and Steelix, to name but a few.
